The Brain and its Working..

The Brain


The human brain is the command center for the human nervous system. It receives input from the sensory organs and sends output to the muscles. The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains. Human brain also has the capability to make correct decisions and choose wisely between any two things.

Interesting Facts About the Human Brain!


  • The human brain is the largest brain of all vertebrates relative to body size
  • It weighs about 1.5 kilograms (3.3 lbs) 
  • The brain makes up about 2 percent of a human’s body weight
  • The cerebrum makes up 85 percent of the brain’s weight
  • It contains about 86 billion nerve cells (neurons) — the “gray matter”
  • It contains billions of nerve fibers (axons and dendrites) — the “white matter”
  • These neurons are connected by trillions of connections, or synapses.

Did you know that the Brain weighed nearly 1.5 kilos? 😱 shocking..

Left Brain VS Right Brain


The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. The left brain controls all the muscles on the right-hand side of the body; and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.

The popular notions about “left brain” and “right brain” qualities are generalizations that are not well supported by evidence. Still, there are some important differences between these areas. The left brain contains regions involved in speech and language (Broca’s area and Wernicke’s area), and is also associated with mathematical calculation and fact retrieval. The right brain plays a role in visual and auditory processing, spatial skills and artistic ability — more instinctive or creative things, A scientist once said — though these functions involve both hemispheres. “Everyone uses both halves all the time.”

Brains of Different Mammals..


Some Diseases Associated with The Brain.

  • Amyotrophic Lateral Sclerosis (ALS)
  • Concussions
  • Creutzfeldt-Jakob Disease
  • Epilepsy
  • Microcephaly
  • Migraines
  • Multiple Scelrosis
  • Stroke
  • Traumatic Brain Injury

These are some of the worst problems that can affect a humans brain, sadly.
